Definition

A geographic classification code that represents the geographic area and, if applicable, the geographic subarea and populated place name covered by an item. The code provides more precise geographic access than the codes contained in field 043. Use separate 052 fields for each geographic area code and any related subarea codes associated with the item. Use subfield ǂd for the name of the geographic area. Use field 552 to record geographic data in note form.

1st indicator

Code source. A value that indicates the code source in subfield ǂa and information in the other subfields.

U.S. Department of Defense Classification. The geographic classification code is from the U.S. Department of Defense Classification system.

7

Source specified in subfield ǂ2. The geographic classification code is from a source other than one specified by the other defined values and for which an identifying code is given in subfield ǂ2.

2nd Indicator

Undefined. The 2nd indicator position is undefined and contains a blank.

ǂa Geographic classification area code

A numeric or alphanumeric code representing the main geographic area covered by an item. If the 1st indicator value is blank, the code is a four-to-six digit number. If the number is longer than four digits, a decimal point follows the fourth digit. To derive the area code, omit the letter G from the LC class number found in the Library of Congress Classification—Class G from the range G3190-G9980. If the 1st indicator value is 7, a code from another source is used and that source is given in subfield ǂ2. Use a separate 052 field for each geographic area code.

ǂb Geographic classification subarea code

A geographic or geopolitical subarea code related to the geographic area coded in subfield ǂa. If the 1st indicator value is blank, the code is an alphanumeric Cutter derived from the Library of Congress Classification—Class G or the expanded Cutter number lists for place names found in Geographic Cutter Numbers. Use a separate subfield ǂb for each geographic subarea code.
